Tire tread



FIG. 1 is a right side perspective view of a tire tread showing our new design, it being understood that the tread pattern is repeated throughout the circumference of the tire, the opposite side being substantially the same as that shown;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view of the right side thereof, the left side elevational view being identical thereto;

FIG. 4 is an enlarged fragmentary front elevational view thereof; and,

FIG. 5 is a further enlarged fragmentary detail view of the right shoulder rib of the tire tread, as shown within the rectangular broken line area of FIG. 4.

The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 2. The broken lines defining the tire sidewall and inner bead, and the broken lines in FIGS. 4-5 defining the boundary of the detail view are for illustrative purposes only and form no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
